Get a full Tricep and Bicep workout for stronger, more toned arms with the Arms Muscle Training System by Slendertone. It activates the biceps (biceps brachii) and triceps (triceps brachii) in the upper arm for a full workout. Use 5 times a week for a guaranteed improvement in upper arm performance in just weeks.

How it Works: The unique construction of the Slendertone Arms Muscle Training System features two pre-positioned on each arm, medical-grade GelPads that cover triceps and biceps muscles. During your toning session, signals from the Slendertone Arms Muscle Training System reach out to nerves where they are most concentrated. These nerves branch out to the triceps and biceps muscles causing them to contract and relax naturally, working all of the muscles at the same time, not just those directly under the GelPads.
